Lucira's Marquise Lab Grown Diamond Solitaires collection brings together rings, pendants, earrings, necklaces and bracelets set with IGI certified marquise cut lab-grown diamonds. The elongated silhouette and pointed ends of a marquise diamond create a larger face-up look per carat than a round brilliant, which is why the cut remains a popular choice for engagement rings and statement jewellery. Every piece here is available in 14KT and 18KT gold, backed by transparent certification and Lucira's lifetime exchange and buyback policy.
About the Marquise Cut
The marquise cut is one of the older fancy diamond shapes, first cut in the eighteenth century for the French royal court and named for its elongated, boat-like outline. A marquise diamond typically carries 56 to 58 facets arranged to maximise brilliance along its length. Because the shape stretches the stone rather than concentrating it in a circle, a marquise diamond can look noticeably larger than a round diamond of the same carat weight, and it tends to make the finger appear longer when set as a solitaire.
What's in This Collection
This collection spans marquise solitaire rings in prong and bezel settings, pave and trilogy engagement rings that pair a marquise centre stone with round or pear accents, pendants and mangalsutras built around a single marquise diamond, drop and cluster earrings, and tennis bracelets set with graduating marquise diamonds. Each design uses IGI certified lab-grown diamonds, so you get the same cut, clarity, colour and carat grading as a natural diamond at a more accessible price point.

Why Choose a Marquise Lab Grown Diamond Solitaire
- An elongated shape that maximises visual size per carat
- A distinctive silhouette that stands apart from round or cushion cuts
- Versatility across solitaire, halo and cluster designs
- The same physical and optical properties as a mined diamond, at a more accessible cost per carat
- IGI certification for verified cut, clarity, colour and carat
How to Choose the Right Marquise Diamond
- Length-to-width ratio: most jewellers consider a ratio between 1.75 and 2.25 the most balanced for a marquise diamond, though personal preference plays a role.
- Bowtie effect: marquise, oval and pear diamonds can show a bowtie-shaped shadow across the centre when the cut is uneven. A well-cut marquise diamond keeps this effect minimal.
- Symmetry: the two pointed ends should align evenly. Off-centre points are more visible on an elongated shape than on a round diamond.
- Setting protection: the pointed tips are the most delicate part of a marquise diamond. Prong tips or a bezel edge at each point help prevent chipping during daily wear.
- Clarity and colour: a VS1 to VS2 clarity with E to F colour is a common balance point, since the elongated shape can make inclusions near the centre more visible than in a round cut.

Direct Answer
A marquise lab-grown diamond solitaire is a single marquise cut, lab-grown diamond set as the centrepiece of a ring, pendant or pair of earrings. The elongated, pointed shape gives it a larger face-up appearance than a round diamond of equal carat weight, and IGI certification confirms its cut, clarity, colour and carat grade.
Frequently Asked Questions
What is a marquise lab-grown diamond solitaire?
It's a single marquise cut lab-grown diamond set as the main stone in a ring, pendant or pair of earrings. The shape is elongated with two pointed ends, giving it a distinctive silhouette compared to round or cushion cuts.
What is the bowtie effect in a marquise diamond?
The bowtie effect is a dark, bowtie-shaped shadow that can appear across the centre of an elongated diamond shape, including marquise, oval and pear cuts. It happens when light escapes through the bottom of the stone instead of reflecting back. A well-cut marquise diamond keeps this effect minimal.
What length-to-width ratio should I look for in a marquise diamond?
A ratio between 1.75 and 2.25 is generally considered the most balanced for a marquise diamond, though the right ratio ultimately depends on personal preference and hand shape.
Are marquise lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds have the same chemical composition, hardness and optical properties as mined diamonds. The only difference is where they are formed, in a controlled lab environment rather than underground. IGI certification grades lab-grown and mined diamonds by the same standards.
How do I protect the pointed ends of a marquise diamond?
The pointed tips are the most fragile part of a marquise diamond. A setting with prongs covering each tip, or a bezel edge, reduces the risk of chipping during everyday wear.
Is a marquise cut a good choice for an engagement ring?
Many buyers choose a marquise cut for its elongated, finger-flattering shape and larger visual size per carat. Whether it suits you depends on personal style, the ratio and symmetry of the stone, and how the setting protects its pointed ends.
